Cannondale cuts to the front of the pack with their 2018 Cannondale Scalpel-Si Black Inc. They pored over every detail to make it one of the lightest full-suspension cross-country bikes in existence, giving it a super stiff, mega-efficient Ballistec HI-MOD carbon frame, oversize BB30 bottom bracket, and a rear 142 x 12mm thru-axle. Techy terrain is no big deal with 100mm of RockShox Monarch travel in the rear. And up front, the 1.5-inch head tube is paired with Cannondale's 100mm-travel Lefty 2.0 Carbon XLR fork for razor-sharp handling and pinpoint line selection. And of course, this XC rocket is dressed to impress with utterly enviable ENVE carbon rims and tubeless-ready Schwalbe tires that spin up fast and grip like scared cats in the corners. Cannondale supplied their own HollowGram SiSL2 cranks, and paired them with Shimano's stunning 1 x 11-speed XTR Di2 drivetrain.
